About

The purpose of this study is to evaluate the clinical safety and efficacy of Gemcitabine plus nab-Paclitaxel chemoradiotherapy and to determine the Maximal Tolerated Dose (MTD) for unresectable locally advanced pancreatic adenocarcinoma.

Full description

Gemcitabine plus nab-Paclitaxel is one of the standard chemotherapy for metastatic pancreatic adenocarcinoma. Gemcitabine plus nab-Paclitaxel realize the favorable anti-tumor effect and tolerable toxicity. Gemcitabine plus nab-Paclitaxel is a promising regimen for concurrent chemoradiotherapy, but the investigators need to know the safety in the case of the concurrent chemoradiotherapy.

Experimental group

Description:

A conformal phase I study using 3 plus 3 method. Chemoradiotherapy while Gemcitabine, Nab-Paclitaxel are administered. Both Gemcitabine and Nab-Paclitaxel are an interventional agents in this arm. Gemcitabine is administered with 30 min intravenous infusion on day 1,8 and 15 every 4 weeks. Nab-Paclitaxel is administered with 30 min intravenous infusion on day 1,8 and 15 every 4 weeks. Radiotherapy (a total dose of 50.4Gy) was delivered in 28 fractions.

Treatment:

Drug: Nab-Paclitaxel

Drug: Gemcitabine
